RULER,

SPECIFICATION formingpart of Letters Patent No. 443,653, dated December 30, 1890.

Application filed April 30, 1890. Serial No. 350,075. (N0 model.)

To aZZ whom it may concern.-

Be it known that we, CHARLES EDWIN J EW- ELL, of Chicago, in the county of Cook and State of Illinois, and MAJOR ROMEYNJEWELL, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Rulers, of which the following is a specification.

Our invention relates to a desk-ruler pro vided with a removable pad or blotter adapted to sustain the edges of the ruler above the surface of the paper.

In the accompanying drawings, Figure 1 is a perspective view of our ruler in operative condition. Fig. 2 is a view showing the frame or ruler proper open to permit the insertion or removal of the pad. Fig. 3 is a perspective view showing the ruler as it may be used after the removal of the pad. Fig. 4 is a cross-section on the line at a of Fig. 1.

Referring to the drawings, A represents the body or ruler proper, constructed of sheetsteel or other appropriate material, with parallel side bars a a, which are of equal width and which are separated, as shown in Fig. 3, by an intervening slot 1) of a width slightly greater than the bars, as and for the purpose set forth in ourapplication of even date herewith. I

In the ruler A, as shown in Figs. 1 2, and 3, the bar a is pivoted at a to the remaining portion of the ruler, so that it may be swung outward from its companion at the free end, as shown in Fig. 2. '1 he free end is provided with a perforation a arranged to close into a slot a where it is held by indentations 0,5, which spring into the hole.

B represents a pad, preferably constructed of blotting-paper or other bibulous material, and which may in special cases be of felt, rubber, or leather. This pad, which is grooved in its edges, as shown in Figs. 2 and l, is inserted into the open ruler, as shown in Fig. 2, so that when the ruler is closed its bars entering the grooved edges hold the pad securely in position, as shown in Figs. 1 and at. The pad serves to maintain the edges of the ruler proper above the paper or other surface on which it is laid to prevent the ruler from shifting about accidentally and to prevent the soiling of the paper, since the pad, when soiled, may be readily removed and replaced by a clean one.

The use of an absorbent pad is peculiarly advantageous when rulingwith ink, since it will absorb the ink with which it may accidentally come in contact, thus preventing the blurring of the lines. It also admits of rapid ruling, as there is no necessity of Waiting for the ink to dry before laying the ruler thereon.

.lVhile we prefer to joint the parts of the ruler together in the manner shown, it is manifest that they may be modified within the range of mechanical skill, provided only they are adapted to open and close in order to permit the introduction of the pad and to secure the same firmly in place.

As the pad projects on both sides of the ruler, the latter may be used either side up. It is to be observed that the edge of the ruler proper projects beyond the pad, so that the latter does not interfere with the use of the pen or pencil in ruling.

When for special reasons itis desired to temporarily dispense with the pad, it maybe removed and the ruler closed, as shown in Fig. 3, in which condition it may be used in the same manner and with the same effects as the ruler described in our concurrent application, in which claim is laid thereto.

Having thus described our invention, what we claim is 1. A ruler having the longitudinal slot or opening therein, in combination with the pad removably seated therein.

2. A ruler provided with alongitudinal central absorbent pad projecting above both surfaces of the ruler.

3. The ruler having the rectangular jointed frame adapted to be opened, as described, in combination with the removable grooved pad.
